Other over Tulsa, OK

The report, as filed

Looked like a falling star then got larger, brighter appeared to be orange sparks behind it sort of like a bottle rocket but by now about the size of what I would imagine a small aircraft in a Terminal predicament would look like. A blue hue appeared behind it around the orange and a whistle sound could now be heard. The blue diminished and the orange sparks started to lessen. Front point had turned into what appeared to be a growing glowing white round light which at first was a small circle of light but dark in the center and progressed into being all white light as the Sparks continue to diminish. By now the whistle turned into a hum that sounded similar to a small aircraft not in distress. When the orange sparks disappeared the hum continued and all that was left was a blueish or green light and a small gold/white/gold/white light and only for a moment a red light. From there it proceeded out of sight, trees were blocking my view, looking and sounding like a small aircraft but moving much faster than any plane that I've ever known of and the hum diminished respectively with the sight of it. It first appeared moving South and barely East from my location as it appeared to drop down and made almost a 90 degrees curve to head East but a little North. About 1/8 of the way towards North from due East.I don't know latitudes and longitudes. It did only travel in two straight very distinctive lines. The turn was maneuvered at the point where the orange sparks were brightest and largest immeditely after the turn is when the blue hue appeared and sparks right after that started to diminish and as the sparks start to diminish is when the whistle turn into a hum. After the Sparks diminished that's when it turned into the bluish light the flashing light which went dark and the red light which only blinked once left only a bluish-green light. White circle appeared just barely before the blue hue was completely gone, the white circle was! gone when the lights started appearing in the other colors at! the fro nt point. The colored lights were in the form of a small triangle with unequal sides when the red light blinked but the white and gold appeared in different relations to the bluish green light. I heard the whistle for about one-and-a-half seconds and about 75% of that time was before the curve and about 25% after. The curve was made instantly. Same amount of time it would take a second hand on a clock to go to the next second after it started to move but before it hit the next second, that's how long it took the curve to be accomplished. If a possible altitude is necessary I can only guess and that would be it appeared from nowhere to begin to fall from the sky and after the curve would be below the average cloud level. It occurred during a clear night, no clouds and could see stars. Please reply to this message? I know I can't leave personal info in a message, but I would like to know what that was or at least that someone has looked into it. And especially for any questions ! or comments that you might have. Thank you.
